Our current depth operating specification for the Thetis Profiler is in water columns ranging from 5 to 100m in depth. The Thetis Profiler has been most rigorously testing in 50 m offshore of Newport, OR, though other systems have been deployed in several other...
FAQs
What are the safety concerns/procedures if the instrument floods? Can the instrument explode?
While a CTD leak can result in a dangerous situation, it is not common. Pressure housings may flood under pressure due to dirty or damaged o-rings, or other failed seals, causing highly compressed air to be trapped inside. For example, a housing that floods at 5000...
Is it necessary to put my instrument in water to test it? Will I destroy the conductivity cell if I test it in air?
It is not necessary to put the instrument in water to test it. It will not hurt the conductivity cell to be in air.If there is a pump on the instrument, it should not be run for extended periods in air.Profiling instruments (SBE 9plus, 19, 19plus, 19plus V2, 25,...
What are the recommended practices for cleaning and lubricating winch cables?
This topic is covered in detail on the UNOLS (University-National Oceanographic Laboratory System) website; see http://www.unols.org/publications/winch_wire_handbook__3rd_ed/06_wire_rope_em_cable_lub.PDF.
What are the recommended practices for splicing cables?
Sea-Bird typically recommends using the Dam/Blok and EverGrip products from PMI Industries. DamBlok makes the electrical splice and EverGrip provides the strain relief on the cable. See an example of how these products can be used.For a quick electrical...
Can I use a pressure sensor above its rated pressure?
Digiquartz pressure sensors are used in the SBE 9plus, 53, and 54. The SBE 16plus V2, 16plus-IM V2, 19plus V2, and 26plus can be equipped with either a Druck pressure sensor or a Digiquartz pressure sensor. All other instruments that include pressure use a Druck...
Where can I get information about safe handling/hazards associated with chemicals used with Sea-Bird equipment, such as Anti-Foulant Devices and Triton X-100 detergent?
See Material Safety Data Sheets (MSDS) for chemicals commonly used with Sea-Bird instruments.
What is Triton? Do I need to purchase it from Sea-Bird?
Triton X-100 is Octyl Phenol Ethoxylate, a reagent grade non-ionic surfactant (detergent). Sea-Bird uses it to help keep our conductivity cells clean and the electrodes wetted and ready for immediate use in water (a dry cell requires a few minutes to become completely...
How do instruments handle external power if internal batteries are installed?
Most Sea-Bird instruments that are designed to be powered internally or externally incorporate diode or'd circuitry, allowing only the voltage that has the greater potential to power the instrument. You can power the instrument externally without...
What is the maximum cable length for real-time RS-232 data?
Cable length is one of the most misunderstood items in the RS-232 world. The RS-232 standard was originally developed decades ago for a 19200 baud rate, and defines the maximum cable length as 50 feet, or the cable length equal to a capacitance of 2500 pF. The...
